review text: Summary: We present a new fault detection and isolation scheme for dealing with simultaneous additive and parametric faults. The new design integrates a system for additive fault detection based on [\textit{A. Castillo} and \textit{P. J. Zufiria}, ``Fault detection schemes for continuous-time stochastic dynamical systems,'' IEEE Trans. Autom. Control 54, No. 8, 1820--1836 (2009; \url{doi:10.1109/TAC.2009.2024568})] and a new parametric fault detection and isolation scheme inspired in [\textit{U. Münz} and \textit{P. J. Zufiria}, Int. J. Control 82, No. 4, 603--619 (2009; Zbl 1162.93399)]. It is shown that the so far existing schemes do not behave correctly when both additive and parametric faults occur simultaneously; to solve the problem a new integrated scheme is proposed. Computer simulation results are presented to confirm the theoretical studies.
